Tests for Python 3.9 fail because SciPy 1.15 requires Python 3.10-3.13 (and NumPy 1.23.5 or greater.)

Python 3.9's end of life is planned for Oct 2025.
Would dropping it already be a problem? @nwlandry

It doesn't make sense to defer this essential fix to align with Python's release schedule. I am good with you removing v3.9 (just make a note in the PR title as well maybe?)

Agreed. I also upgraded NumPy as required by SciPy.

This was an important bug to fix, but for some reason I only ever noticed it in "email-enron", and even then, only the smaller eigenvalues were affected. So hopefully, the bug hasn't had too much of an impact.
